Numeral 1 `indicates a window which `is adapted to be'.y r'eciprocatedvertically in :a suitable"frame,the lowerpar't ofwhich is indicated at2; Numeral 3 indicatesa plate which is mounted on and secured to thelower-part 2 in any desirable manner while g. 2 `1s ak front yeleva-tionof'one of the slidable plates employed onA the lowercon'f i' to the`"several, rfigures 4 indicates a cover platemwhi'ch is screwed to saidvplate by suitable screws 5 and which forms with-sindy lute 3 a' housingcontaining a clutchv 'and other` mechanism to be presently described. Avertical depending bafr or strap Slis fastened at its upper end to theplate 3 and at its lower end to a` cross-bar 7 which is detachablsecured to theilside 4walls of other parts o thewindow we The ybar 6 isyprovided adjacent its-lower end with twov slots8 'and 9 respectively,the slot 8 being so cut in the material as to' form an arm 10. 11 and 12indicate vertically slidabl'e plates each of which2 is provided withdepressions 13rv pressed vinwardly from the metal and actingv asanti-frictionmem- -bers slidably engaging the bar or strap 6. The upper`ends of said plates 11 and 12 are bent'inwar'dly into engagement witheach other Vand within the Slot'S to form a shoulder 14. A compres'sion' spring 15 encircles the arm 10 an the u per .inwardly bentends-"of Athe platesr and) bears against the y shoulder 14 andactstofpress' or force said4 ig. 'l is afrontelevatlon of the windowvplates. downwardly on the bar or strap 6.

y A bolt 16 extends through the slot 9 in the barn and Ialso throughsuitable annular openings in the plates: 1'1 and 12. Said boltis'prOVidedwith ears or shoulders-17 engagingin slots 18 in plate12-which slots communicateywith the bolt-receiving opening in saidplate.The engagement of'said ears with vsaid slotsA acts to 'prevent rotationof'said bolt. The hub portion 19 of a lower rotatable sprocket 20 ismounted on the en' larged annular portion 21'o'fA the bolt 16, a

longitudinal movement of said sprocket on said portion 21 bein preventedby la flange 22 on said bolt and y an annular ridge 423l on theplate 12whichfis" pressed Aoutwardly from Athe, metal and which engages the sideof the hub portion 19. `A` nut 24 is screwed i on the end of thebolt andholds vthe plates together'as is manifest, a washer 25 prefer ablybeing-interposed between said `nut and 4late. 11 and seatm onf-ashoulder 26 formed y a depression? lWit whichsaid plate is pro` v1ded. f

An endless driving chain 27 passes over an upper sprocket 28, which ismounted on the plate?) in a manner to be presently described,saidchainibein'g heldtaut by the actiony of the spring 15 which, as hasbeen described,

loo

presses downwardly against the vertically slidable plates 1l and 12carrying the lower sprocket 20, thus preventing the chain from runningoff said sprockets. The chain 27 is connected to the window 1 by meansof a roller stud 29 engaging in a slot of a plate 30 which is secured toand depends from the lower side of the window. A handle 31 is mounted ona housing and connected with mechanism within said housing formed by thecover plate 4 and plate 3 whereby rotation of said handle will rotatethe upper sprocket 28, thereby cansino' the chain 27 to travel aroundthe upper and lower sprockets thus effecting a raising and lowering ofthe window depending on the direction of rotation given the handle.

Numeral 32 indicates a crank shaft which is provided with enlarged andreduced hub portions 33 and 34 rotatably received by an annular neck 35pressed out from the plate 4 and a removable bearing 36 respectivelywhich bearing is received and held within an o ening in the plate 3.(See Fig. 6.) The iandle or crank 3l is secured to the end of said shaftin any desirable manner. The shaft is provided with a substantiallyrectangular-shaped driving-member actuator 37 preerably integraltherewith and having fiat sides and rounded ends and also end flanges 38slidably fitting intermediate the plate 4 and ae fixed clutch member 39.The flanges 38 act to prevent rocking or dis lacement of a clutchdriving member 42 to e presently described. y

The fixed clutch member 39 is provided with pins 40 extending throughdepressions in the plate 4 the ends of said pins being riveted 4over onsaid plate within said depressions, whereby the clutch member issecurely held against movement. Said clutch mem ber is also providedwith an enlarged opening 4l extending tlierethrou h having a serrated ortoothed ed e as in icated. i

The driving mem er of the clutch is indicated at 42 and is provided withoutwardly projecting ins 43 and an opening 44 having an upper fat wall,rounded side walls and a lower wall having an irregular or cam surface.(See Fig. 9.) The lower portion of the driving member is also providedwith teeth 45 adapted to interlit with the teeth ot the opening 41 ofthe iiXed member 39. The openin r 44 is adapted to receive the actuator37 on t ie shaft 32 and the opening 41 of the fixed clutch member 39receives the driving member 42, the fixed clutch member and drivingmember 42 both lying in the saine plane. Then the handle or crank on theshaft 32 is not rotated or operated one of the flat sides of theactuator 37 engages the upper fiat wall of the opening 44 while itscurved ends engage the rounded side walls of said opening as shown inFig. 5.

Numeral 46 indicates the driven ymember loosely carried on the shaftandwhich comprises a flat disk provided ,with slots 47 therein slidablyreceiving the pins 43 of the driving member 42. (lne of said slotscarries a spring 43 beariii against one of the pins 43 and acts toretain the driving member 42 in the position shown in Fig. 5 with itsteeth 45 lockingly engaging the-teeth of the fixed member 39, wherebyrotation of the shaft 32 will be prevented if rotation is attempted romthe end adjacent the hub portion 34 as is obvious.

The driven member `46 is provided with outwardly projecting pins 49entering and interiitting with suitable openings in a pinion 50 looselymounted on the shaft, said pinion meshing with a large ear 51. When thecrank or handle is rotate the part 37 of the shaft takes the positionshown in Fig. 9 or at right angles to said-position depending on thedirection of rotation of the crank or handle. As the pa'rt 37 may notcompletely rotate within the opening 44 it forces the driving memberagainst the action of the spring 48 to move in a direction whereby theteeth 45 will become disengaged from the teeth of the fixed member 39,after which the member 42 will rotate with the shaft. Rotation of theshaft thus effects a rotation of the driven member 46 due tothe pins 43en gaging in the slots 47. When the driven member rotates the pinion 50and ,large gear 51 likewise rotate because of the connection betweenthese parts as hereinbefore described. When the crank or handle isreleased .the parts automatically lock as the spring48 bearing againstone of the pins 43 acts to move the driving member 42 into its firstposition whereby its teeth 45 will engage the teeth of the fixed member39, the part 37 being also forced back into normal position shown inFig. 5. For all practical purposes the driven member 46 and pinion 50may be considered one part, they being constructed of two parts merelyfor convenience of manufacture. y

The gear 5l is fixed to a shaft 52 provided with a flange 53 acting as astop to prevent a longitudinal movement of the gear thereon. One end ofsaid shaft 52 is hollowed out as at 54, this end of the shaft beingsupported by a depressed support 55 pressed inwardly from the metal ofthe plate 4 and entering the liollowed out portion 54. The other end ofthe shaft is mounted in an annular neck 56 pressed out from the metal ofthe plate 3 and forming a bearing for said shaft, a washer 57 beingpreferably interposed between said bearing and shaft. The plate 3 isalso provided with an annular ridge or bead 58 pressed inwardly from theplate and acting as an anti-friction support slidably engaging the sideof the gear 51 and adapted to prevent rockin thereof. The end of theshaft 52 is reduc and relll() llO ceivesthe sprocket 28 which isrot-atable `therewith and which is adapted to engage a shoulder 59 onthe shaft to prevent a lonwith a head 61 received by the recess54.

The opposite end of said bolt carries va washer 62 adapted to preventremoval of the sprocket from the shaft.

The plate 4 is provided with an inwardly extending lu 63 vcut from themetal to which one en of a counte'rbalancing spring 64 is secured orhooked, the other end of said spring being secured or hooked to a lug 65on the gear 51. The sprin is supported andprevented from sprea inoutwardly by additional lugsy 66 on sai gear and is prevented from toogreat an inward movement, which might tend to interfere with therotation of the shaft 52, by a semiciroular shapedV ridge or` bead 67pressedv inwardly from the plate. The counterbalancing spring per se isold although in so far as we are aware the Vparticular manner ofmounting and holdin the same in proper position as shown an 4describedis new. The function of the spring is to assist in the raisingof thewindow, the spring befl 'ino' wound up by thel lowering thereof.
